These Protein Peanut Butter Cookies are soft, chewy, and made with simple ingredients like peanut butter, protein powder, and chocolate chips. They’re naturally flourless, easy to make, and perfect for a quick snack, healthy dessert, or post-workout treat.
As a certified nutrition coach, I’m always looking for ways to make everyday treats a little more balanced. These protein cookies are one of my favorite snacks because they’re easy to make, satisfy my sweet tooth, and provide extra protein to help keep me full. I usually make a batch at the beginning of the week so there’s always something homemade to grab when I need a quick snack.
For a lower-calorie option, try using baking sweetener (erythritol) instead of coconut sugar, and also opt for dark chocolate chips instead of semi-sweet.
What Makes These Protein Cookies a Better Choice?
These cookies are made with simple ingredients that add both flavor and nutrition. Peanut butter provides healthy fats and protein, while protein powder gives each cookie an extra boost, making them more filling than traditional cookies.
Since they’re made without flour, they’re naturally gluten-free when made with certified gluten-free ingredients. They’re a great option when you’re craving something sweet but want a snack that’s a little more balanced.
Ingredients notes and substitutions
Below is a list of ingredients you are going to need to make these cookies. Full measurements are listed further down below in the recipe card.
- Peanut butter: Use creamy, natural peanut butter for best results. Avoid brands with added oils for better texture.
- Protein powder: Whey or plant-based protein both work. Vanilla protein adds a slightly sweeter flavor.
- Chocolate chips: Dark or semi sweet chocolate chips work best.
- Coconut sugar: Sweet, granulated coconut sugar is a great refined-sugar-free option to keep these cookies sweet and healthy.
- Eggs: This recipe calls for 2 eggs to bind the ingredients. For vegan cookies, use flax eggs.
- Baking soda: Baking soda is very helpful to give cookies that soft but crunchy texture.
Best Protein Powder to Use
Whey protein works best in this recipe because it creates a soft, chewy texture. If you’re using a plant-based protein powder, the dough may be a little drier, so you may need to add a splash of milk. Every protein powder absorbs moisture differently, so don’t be afraid to adjust the dough slightly until it’s easy to scoop.
How To Make Peanut Butter Protein Cookies
This recipe is so easy that you will want to make it again and again. I love baking these tasty chocolate chip cookies whenever I am craving something sweet and filling.
First, prepare your workstation and measure your ingredients. Next, preheat the oven to 350 degrees Fahrenheit. Line a baking sheet with parchment paper or a nonstick baking mat.
Make the dough: In a large bowl, whisk together the eggs, peanut butter, and coconut sugar until fully combined and a paste-like texture forms.
Add in protein powder: Next, add in the protein powder and baking soda. Mix again to combine until a soft dough forms.
Fold in the chocolate chips and combine to incorporate.
Shape the cookies: Scoop 1 ½ tablespoon-sized mounds of dough. Space them out evenly on a baking sheet. Approximately 1 ½ inches apart. Wet your fingers with water, then gently press the mounds into cookie shapes.
Bake: Bake the cookies in the preheated oven for 10 minutes or until the cookie edges are brown. Once fully baked, let the cookies sit on the pan for 5 minutes, then transfer them to a cooling rack. Repeat the process with the remaining dough. Enjoy warm with a chilled glass of milk!
Common Mistakes to Avoid
- Overbaking the Cookies: Protein cookies continue to cook as they cool. Remove them from the oven as soon as the edges are lightly golden to keep them soft.
- Using a Different Protein Powder Without Adjusting: Not all protein powders behave the same way. If your dough seems dry or crumbly, add a tablespoon of milk until it reaches the right consistency.
- Skipping the Cooling Time: Let the cookies cool on the baking sheet for a few minutes before moving them. They’ll firm up as they cool and be less likely to break apart.
Easy Variations
There are many ways to customize these cookies using ingredients you already have.
- Swap the chocolate chips for white chocolate chips.
- Stir in chopped pecans or walnuts for extra crunch.
- Add a tablespoon of cocoa powder for a richer chocolate flavor.
- Sprinkle flaky sea salt on top before baking.
- Replace the peanut butter with almond or cashew butter.
- Add a pinch of cinnamon for extra warmth.
Common Questions
You can easily use a chopped chocolate bar filled with milk chocolate with almonds, or opt for white chocolate mixed with a candy cane or peppermint.
Your oven may be too hot, or the dough may have been overmixed. These are two factors that can affect the shape of the cookies!
Yes, but the texture will change. Protein powder helps bind the cookies and adds structure. You can use almond flour or oat flour instead.
The most common reasons are overbaking or using a protein powder that absorbs more liquid. Bake just until the edges are set, and adjust the dough with a little milk if needed.
I like to use Whey protein because it creates a softer cookie, while plant-based protein makes them slightly denser. But both will work.
Yes. Plant-based protein powders tend to absorb more moisture than whey, so you may need to add a tablespoon or two of milk if the dough seems dry.
Storing Recommendations
Allow the cookies to cool before storing. They can stay covered on the kitchen counter for up to 3 days. Place them in a sealed container in the fridge for up to 10 days. You can freeze for up to 3 months.

Turned out perfectly! Delicious and easy to make. Thank you for the recipe!
Thank you so much.
Can i use maple syrup or something else to substitute coconut sugar?
Yes. But it may make the dough a bit loose, so just adjust it by adding a bit more protein powder, or maybe almond flour.
Love these cookies! I add pecans and a little almond flour
Perfect. Sounds yummy.
I made these and they were amazing! Can they be made with Stevia instead of coconut sugar please?
Hi Kate. I haven’t tried them with stevia, but if you are referring to the ones used for baking, it should work.
I usually don’t post comments, BUT….
I just finished making these protein chocolate chip cookies… OMG!!! These are the best cookies I’ve ever had, so delicious! Soft & chewy, perfect! I definitely will be making a couple more batches to freeze & have handy. A BIG hit with the hubby! Thank you for a GREAT recipe! 10 out of 10
Thanks Dori. I am so glad you all loved it. Yay
It calls for 2 scoops of vanilla whey powder. What does that equal in cups of tablespoons? I do not have a scoop.
My scoop is almost 1/4 cup. you can use 1/2 cup
I used almond butter and chopped dark chocolate
Halved the recipe and used ice cream scoop to measure to bake
7 nice sized bakery style cookies that tasted amazing
glad you loved them. Yay
Mine were very greasy I’m assuming from my peanut butter. Also didn’t have any sugar alternatives other than swerve brown sugar!
Wish they turned out for me!
Yes, it all depends on the peanut butter. I haven’t tried it with swerve so I am not sure.
Can you use substitute plant based protein powder for whey protein powder?
Yes you sure can.
Hello,
The nutrition information is for 1 cookie, which is 1 serving, as I am guessing? Am I correct?
They are delicious btw!
Hi there. Yes per cookie
can I substitute to protein powder for something else? or can I omit it?
You can swap it with oat flour or almond flour.
These came out great! I used part monk fruit, part sugar, and only had crunchy peanut butter. Ended up making about 21 cookies. So yummy! Thanks!
Perfect!
